Inductive Loads

When everything was ready i found out that when I switch off the pump or the humidity generator the main controller resets.

This was due to the fact that when I switch off the power to the load, the field around the coil compress and generate high voltage.This high voltage makes a spark in the contacts of the relay and create a disturbance in the power supply or in the reset line of the controller.

To solve the problem I have to use so called RC Snubber.This is simple series RC filter connected parallel to the load.

I used 100nF/275V capacitor and 110ohm resistor.

No problems for now :).
